Speedy the Visible Light Ray, travels through space
real quick.
And if you try to touch him, youll find out that he's not thick.
All other E M wavelengths, were left out in the dark to cry,
While Speedy the Visible Light Ray was really lighting up the sky.

Then one foggy physics eve, Roemer came to say,
"Speedy with your light so bright, let me time your speed tonight."
Then all the other wavelengths, said with all their energy,
Speedy the Visible Light Ray, we'll see you in the lab-'ra-tor-Y!!
